Abstract

The utility model discloses a fixed curved pipe clamp served as a sliding block in a boiler, which comprises a pipe clamp and a latch. The pipe clamp consists of two arcs, wherein the two arcs internally provided with semicircle holes are connected side by side to form an integrated piece with two to four holes. The connection part of the two arcs is provided with a square groove and the square groove passes through the semicircle holes. The latch is provided corresponding to the square groove. The fixed curved pipe clamp serves as a sliding block in a boiler has the effects of restoration and positioning. The fitting surface of the pipe clamp with a pipe is weldless and is in a sliding state, thus has no damage to the protopipe. When a pipe of a boiler panel in a boiler of any grade or any capacity cannot be in place due to dequeuing, dislocation or deformation during the operation of the boiler, the curved pipe clamp can be used for fixing the pipe. The fixed curved pipe clamp can also be used for preparing batches of universal parts in advance as substitutes for sliding blocks before the pipe of the boiler panel is utilized. The fixed curved pipe clamp is convenient to assemble and use.

Description

Play the fixedly arc pipe clamp of sliding shoe effect in the boiler

Technical field

The utility model relates to a kind of pipe clamp, relates in particular to the fixedly arc pipe clamp that plays the sliding shoe effect in a kind of boiler, belongs to fixing tube servicing unit technical field in the boiler.

Background technology

For a long time, the tube panel of the full wall superheater in the boiler body, pendant superheater, high temperature superheater, high temperature reheater, low-temperature reheater generally all will adopt the form of sliding shoe to fix the location.Sliding shoe generally shifts to an earlier date pre-buried being welded in and is assembled into tube panel on the pipe, and material is a stainless cast steel part, according to operation cigarette Wen Dingcai in the stove, generally all uses ZG ₁₆Cr ₂₀Ni ₁₄Si ₂Or ZG ₁₂Cr ₁₈Ni ₉, the general 6 ~ 9mm of thickness.

Though utilized sliding shoe to fix tube panel; But the boiler unit is after long-time running, and power plant's burning coal and former design coal exist than reasons such as large deviations sometimes; Cause the tube panel pipe of the full wall superheater in boiler body top, pendant superheater, high temperature superheater, high temperature reheater, low-temperature reheater to fall out, misplace; The distortion pipe is many, and each light maintenance, overhaul all can detect, and needs after the detection to change or proofread and correct; But, therefore change or proofread and correct very effort because sliding shoe and pipe way are the relations of pre-buried welding.

The utility model content

The purpose of the utility model is: a kind of fixedly arc pipe clamp that in boiler, plays the sliding shoe effect is provided, makes things convenient for the in time thoughtful reparation location of power plant, improve boiler operating efficiency, thereby can effectively solve the problem that exists in the above-mentioned prior art.

The purpose of the utility model is to realize through following technical proposals: the fixedly arc pipe clamp that plays the sliding shoe effect in a kind of boiler; Comprise pipe clamp and latch; Said pipe clamp is two to four void shapes that the circular arc of two interior tool semicircle orifices connects as one side by side; Be provided with the square groove that is through to semicircle orifice in the junction, said latch is corresponding with square groove.

As a kind of optimal way, wherein: said pipe clamp is divided into pipe clamp and lower tube clip, and both sides had breach when said upward pipe clamp and lower tube clip closed up.

As a kind of optimal way, wherein: said upward pipe clamp and lower tube clip are one to three half-circle-arc shape that pitch connects as one.

As a kind of optimal way, wherein: the thickness of said pipe clamp is 8-10mm, and width is 52-60mm.

Compared with prior art; The beneficial effect of the utility model: the utility model fixedly curved pipe is clipped in and plays a part sliding shoe in the boiler and repair the location, and the non-welding of the mating surface of pipe clamp and pipe is in sliding mode; Do not hinder female pipe; Body tube panel pipe is fallen out, misplaces, is out of shape can't be in place the time after the boiler operatiopn of grade capacity in office, and available this arc pipe clamp is used for fixing, also can be before boiler tube panel pipe uses; Make the effect that the generalization part substitutes sliding shoe, its assembling, easy to use in advance in batches.

Description of drawings

Fig. 1 is the structural representation that plays the fixedly arc pipe clamp of sliding shoe effect in the utility model boiler;

Fig. 2 is the A-A cross-sectional view among Fig. 1;

Fig. 3 is the cut-away section structural representation of pipe clamp among Fig. 1;

Fig. 4 is the B-B cross-sectional view among Fig. 3.

Among the figure: 1-pipe clamp, 2-latch, the last pipe clamp of 11-, 12-lower tube clip, 13-square groove, 14-semicircle orifice, 15-breach.

The specific embodiment

Below in conjunction with specific embodiment and accompanying drawing the utility model is further described.

Disclosed all characteristics in this specification, or the step in disclosed all methods or the process are except the speciality of mutual repulsion and/or the step; All can make up by any way; Only if special narration all can be replaced by other equivalences or the alternative features with similar purpose, promptly; Only if special narration, an embodiment in a series of equivalences of each characteristic or the similar characteristics.

Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4; The fixedly arc pipe clamp that plays the sliding shoe effect in the utility model boiler comprises pipe clamp 1 and latch 2; Two to four void shapes that the circular arc that said pipe clamp 1 is two interior tool semicircle orifices 14 connects as one side by side; Be provided with the square groove 13 that is through to semicircle orifice 14 in the junction, said latch 2 is corresponding with square groove 13.

Specifically, said pipe clamp 1 is divided into pipe clamp 11 and lower tube clip 12, and both sides had breach 15 when said upward pipe clamp 11 closed up with lower tube clip 12; The said pipe clamp 11 of going up is one to three half-circle-arc shape that pitch connects as one with lower tube clip 12; The said thickness of going up pipe clamp 11 and lower tube clip 12 is 8-10mm, and width is 52-60mm.

In accompanying drawing 3, last pipe clamp 11 is that two pitches connect as one with lower tube clip 12, forms the void shape of four circular holes, and the said thickness of going up pipe clamp 11 and lower tube clip 12 is 8mm, and width is 52mm.

The use of the utility model is following:

When the boiler unit after long-time running; Sometimes power plant's burning coal and former design coal exist than reasons such as large deviations; Cause the tube panel pipe of the full wall superheater in boiler body top, pendant superheater, high temperature superheater, high temperature reheater, low-temperature reheater to fall out, misplace; The distortion pipe just can use this pipe clamp for a long time.

The material of pipe clamp and pin is stainless cast steel part, according to operation cigarette Wen Dingcai in the stove, can select ZG for use ₁₆Cr ₂₀Ni ₁₄Si ₂Or G ₁₂Cr ₁₈Ni ₉, the size of pipe clamp is customized according to the tube outer diameter specification; Square groove in the pipe clamp adds man-hour, and pipe clamp pairing processing marked is convenient to pin and is passed, and pin can unify to cast common-use size, the foundry goods rounding off.

The hole wall of semicircle orifice and pipe are fitted to holding together in the pipe clamp, and upper and lower pipe clamp can with pin welding positioning instant at the square groove place to after holding together.Behind the location; The mating surface of upper and lower pipe clamp and pipe does not weld, and is in sliding mode, does not hinder female pipe; Play a part sliding shoe; Body tube panel pipe is fallen out, misplaces, is out of shape and can use this " arc pipe clamp " structure to manufacture and be used for fixing can't be in place the time after the boiler operatiopn of grade capacity in office, also can make the effect that the generalization part substitutes sliding shoe in batches, and is easy to assembly.

The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
